Refactor services for better readability

**Problem**
When working with utils, the error messages could be more descriptive.

**Suggestion**
Improve error handling and add detailed error messages.

**Context**
This would help with debugging and maintenance.

Start by locating the services and utils involved in error handling, then read the current error paths and messages. Determine which messages lack useful debugging context and define the affected scope before changing anything. Done means the relevant errors are more descriptive without changing their underlying behavior.
